    22 <para>The libungif package contains libraries for reading all
    23 <acronym>GIF</acronym>s and writing non-compressed ones as well as programs for
    24 converting and working with <acronym>GIF</acronym> files.  The libraries are
    25 useful for any graphics program wishing to deal with <acronym>GIF</acronym>
    26 files while the programs are useful for conversion purposes as well as cleaning
    27 up images.</para>
    28 
    29 <para>The reason libungif only writes non-compressed <acronym>GIF</acronym>s
    30 is due to a legal issue with <acronym>LZW</acronym> compression (which Unisys
    31 claims a patent on). Reading <acronym>GIF</acronym>s is not a problem as the
    32 decompression routines do not seem to be limited in this way.  Note that this
    33 has in the past been disputed.  The best way to avoid this whole mess is to
    34 simply use libungif for looking at <acronym>GIF</acronym> images on the web,
    35 while in any pages which you design, use the open source <acronym>PNG</acronym>
    36 format instead (which uses, not surprisingly, the libpng library) which has no
    37 patent issues at all.</para>
